The Mercedes error code c1401 indicates a problem with the front right wheel speed sensor. This sensor plays a crucial role in monitoring both the anti-lock braking system and vehicle speed. If the sensor malfunctions due to wear, disconnection, or debris impact, the ABS Light may illuminate, signaling the need for sensor replacement. Without the wheel speed sensor's aid, American drivers could face multiple speeding tickets. This vital component, also known as an ABS sensor, is affixed near the drive tire's hub and oversees various vehicle functions, including traction control, anti-lock braking systems, and speed measurement.
In American terms, when you see fault code C1401 on a Mercedes, it indicates a problem with the ABS pump, which has failed.
